The steam was invented BY James Watt, who worked FOR many years before he could make the instruments WITH which he perfected his machine. AT first he worked WITH primitive tools so he could not make his engine well-regulated. The old machine was kept going BY a boy who stood by it and let IN the air WITH means of which the steam was condensed at every revolution. WITH this machine, though it was imperfect, some work was done and it had been used BY a large mine-owner (шахтовладелец) to pump out the water. The first efficient steam-engine was made BY a Birmingham firm and it was soon used BY nearly every manufacturer. The revolution in industry made WITH this machine was extremely great.
